Reducing heavy drinking in college males with the decisional balance: Analyzing an element of Motivational Interviewing Joseph W. LaBriea,*, Eric R. Pedersena, Mitch Earleywineb, and Hutson Olsena aDepartment of Psychology, Loyola Marymount University, 1 LMU Drive, Los Angeles, CA 90045, United States bUniversity of Southern California, United States Abstract The decisional balance, a brief detailing of the advantages and disadvantages of behavior change, serves as a key component to interventions in Motivational Interviewing. The impact of this component alone is not well understood. Forty-seven men completed a Timeline Followback interview assessing alcohol consumption and unsafe sexual practices. They then completed a decisional balance, listing the Pros and Cons of decreasing their drinking, but not one for safer sex. One-month follow-up data showed that they had statistically significant and clinically meaningful increases in their motivation to alter drinking and decreases in the number of drinks that they intended to drink, the actual drinks consumed per month, the days per month that they drank, their maximum number of drinks consumed on one occasion, and their average number of drinks per occasion. They did not alter their sexual behavior or their motivation to increase safe sex behavior. These results suggest that the decisional balance plays an important role in Motivational Interviewing and could serve as a quick and efficient intervention by itself. Keywords Motivational Interviewing; Alcohol use; Decisional balance; College students At least forty percent of college students drink heavily (O’Malley & Johnston, 2002) and experience negative alcohol-related consequences (Wechsler & Nelson, 2001). Students who drink heavily report alcohol impairs their academic and personal lives, leading to disruption of their sleep and studies as well as property damage and verbal, physical, or sexual violence (Engs, Diebold, & Hanson, 1996; Wechsler, Davenport, Dowdall, Moeykens, & Castillo, 1994; Wechsler, Lee, & Kuo, 2000; Wechsler, Moeykens, Davenport, Castillo, & Hansen, 1995). Universities attempt to reduce the prevalence of drinking and alcohol-related problems by implementing alcohol-free campuses, dorms, or events; requiring student attendance of alcohol education classes; and providing counseling to students with potential substance abuse problems (Wechsler, Seibring, Liu, & Ahl, 2004).

Page 2 targeting misperceptions of campus drinking norms, such as social norms marketing campaigns (Far & Miller, 2003; Perkins & Craig, 2002), as well as interventions that NIH-PA Author Manuscript NIH-PA Author Manuscriptchallenge NIH-PA Author Manuscript alcohol expectancies (Darkes & Goldman, 1993, 1998, Dunn, Lau, & Cruz, 2000), have shown promise in decreasing problematic drinking. Similarly, interventions combining both the style and techniques of Motivational Interviewing (Miller & Rollnick, 2002) reduced drinking in identified problem drinkers (Baer, Kivlahan, Blume, McKnight, & Marlatt, 2001; Baer, Marlatt, Kivlahan, Fromme, & Larimer, 1992; Borsari & Carey, 2000; Marlatt, Baer, Kivlahan, Dimeff, Larimer, Quigley, et al., 1998). Motivational Interviewing (MI) is a non-judgmental, client-centered style of counseling founded on the basic principles of expressing empathy, developing discrepancy, rolling with resistance, and supporting efficacy. Interventions designed to help motivate students to change problematic drinking behavior often follow these principles. Helping students develop discrepancies between their behavior and their goals, motivating them to reduce problematic drinking, and helping them prevent relapse into problematic drinking behavior are the essential strategies underlying MI-based interventions with college students. Motivating individuals to change problematic behavior stems from the transtheoretical model of behavior change (Prochaska & DiClemente, 1986), which posits stages of change. These include pre-contemplation, contemplation, preparation, action, and maintenance. Each successive stage represents increased motivation for continued behavior change. Those in the action stage are ready and willing to change. Since many participants in college interventions will not be ready to initiate change, it is essential to help them reach the action stage during interventions. Motivational Interviewing is especially useful for motivating individuals who may not recognize a problem or may be ambivalent about changing their drinking behavior to make a decision to change (Miller & Rollnick, 2002). One MI strategy designed to build motivation for changing behavior is the decisional balance. The decisional balance, a procedure derived from Janis and Mann’s (1977) decision-making model, assumes that sound decision-making involves careful scanning of all relevant considerations that enter into a decisional “balance sheet” of comparative potential gains and losses. Empirical tests of the decisional balance procedure reveal two factors: “Pros” or benefits of changing the behavior and the “Cons” or costs of changing the behavior (Velicer, DiClemente, Prochaska, & Brandenburg, 1985). The decisional balance is a tool used in MI to help clients explore and resolve their ambivalence about changing. Individuals list their own personal reasons for and against changing their behavior. The decisional balance penetrates a participant’s state of ambivalence, clarifies competing motivational factors, and encourages the person to consider the possibility of change. MI posits that constructing a decisional balance sheet is not merely a passive assessment of current motivation, but that is also likely to influence motivation (Miller & Rollnick, 2002). Often, however, the decisional balance is used as one tool among many in brief MI interventions. Neighbors, Larimer, and Lewis (2004) suggest that one of the methodological problems with existing brief intervention research is that the interventions themselves Addict Behav. Author manuscript; available in PMC 2014 October 31. LaBrie et al. Page 3 involve multiple components, which prohibits the evaluation of unique contributors. Individual components of brief interventions have received little scrutiny despite the obvious NIH-PA Author Manuscript NIH-PA Author Manuscriptpractical NIH-PA Author Manuscript and theoretical reasons for examining them (Zweben & Fleming, 1999). The current study attempts to determine the effectiveness of a unique component, the decisional balance procedure, in motivating and initiating change in drinking behavior among high-risk male college students. While other motivational interventions have been successful in producing reductions in drinking (Baer et al., 2001; Baer et al., 1992; Borsari & Carey, 2000; Marlatt et al., 1998), the current study uses the decisional balance only (in concert with the non-confrontational style of open-ended questions of MI), to increase readiness to change problematic drinking behavior. The study is a within-persons design and it is hypothesized that the decisional balance intervention will significantly increase participants’ motivation to change drinking behavior, while not affecting motivation to change another assessed health behavior—risky sex. By assessing two problem behaviors but performing a decisional balance on only one, we can test if any alterations in the behaviors stemmed simply from assessment rather than the decisional balance. If this brief and simple procedure decreases drinking, the decisional balance can be used widely on college campuses. 1. Methods 1.1. Participants Male college students (N =315) responded to flyers seeking research participants for a study on attitudes and behaviors towards drinking and sexual activity. Initial respondents were screened using a phone interview. To obtain at-risk individuals, only those who drank more than twice a week and who had intercourse (vaginal or anal) with two or more heterosexual partners in the previous
